Letter from Thomas Gold to Dr B C Low, Enrico Fermi Institute, University of chicago, Chicago, Illinois Gold was very interested in the conclusions of Low's paper. He believes that this discussion is indeed the basis of the flare phenomenon, except that he believes that motion of the 'feet' is as likely to be a major cause of reaching instabililty as the dissipative changes. He is enclosing a discussion of that point. 9 April 1973
